What is Single Bag Filter Housing?
FiltEdge’s Single bag filter housing is a kind of pressure filtration equipment with simple structure and flexible operation. Its core consists of metal cylinder, support basket and filter bag, which is easy to disassemble and maintain.
In order to cope with complex working conditions, the unit can be used in series or parallel:
Tandem: Intercepts impurities step by step, protects the fine filter element and prolongs the life of consumables.
Parallel connection: Realize high flow rate processing or switching filter bags without stopping, guaranteeing 24-hour continuous operation of the production line.
This can help you dramatically reduce O&M costs, minimize downtime for maintenance, and tightly control the purity of your material to improve finished product yields.
FiltEdge offers in-depth customization. Whether it’s special inlet and outlet orientations, non-standard pressure ratings, or special materials for highly corrosive fluids (e.g., Hastelloy or fluorine lining), we’ll make sure your single bag filter housing is perfectly suited to your production needs.
Types of Single Bag Filter Housing
The logic of selecting a single bag filter housing is not about the housing, but about how you deal with leakage, pressure drop and maintenance frequency. For your different fluid characteristics and pressure fluctuations, we provide you with the following selection options based on thousands of field operating data to ensure that each unit is precisely adapted to your process.
Top Entry Single Bag Filter HousingLiquid is pressed in from directly above, using the gland to act directly on the sealing ring of the filter bag. With CNC-machined sealing grooves, side leakage is measured at 0%, even when you’re operating at sustained high pressures up to 1.0 MPa. If you’re responsible for high-value chemical fluids or precision purification tasks, this is the product for you.
Quick-Open Single Bag Filter HousingIf you are faced with high impurity levels and frequent changeover of consumables, don’t waste your time manually tightening bolts. The three-jaw locking or clamping design allows your operators to perform maintenance with their bare hands in less than 120 seconds, dramatically improving the turnover rate of your entire production line.
Small Flow Single Bag Filter HousingFor small-scale production of 1-10 m³/h, this series is ultra compact and features a Ra＜0.6 μm mirror-polished interior. It can help you to take care of those materials extremely sensitive to the amount of residue liquid filling or laboratory precision small sample filtration tasks.
Side Entry Single Bag Filter HousingA hot seller with flexible inlet and outlet positions, it is cast or spin molded for structural stability. With extremely robust operation at 0.6-1.0 MPa for cooling circulating water or conventional primary filtration, it’s the right balance for keeping production costs under control on a limited budget.
Corrosion Resistant Single Bag Filter HousingFor your extreme acid/alkaline (pH) fluids, we offer durable models lined with PFA/ETFE or pure PP. This construction is a direct match for strong oxidizers and virtually all types of inorganic acids, ensuring that your single bag filter housing will not stress crack or corrode and never safely perforate in harsh working chemical environments.
Features of Single Bag Filter Housing
In addition to the conventional specifications of single bag filter housing, your on-site piping direction, special corrosive environment or stretched installation space is the core of our solution. Whether you require a customized inlet/outlet location or a special anti-corrosion coating, we can achieve seamless integration according to your drawings.
With CNC-machined seal grooves and annular compression devices, you can achieve the demanding goal of zero side leakage at 1.0 MPa. This ensures that 100% of the fluid must pass through the filter bag, helping you maintain a high level of precision filtration.
With the optional three-jaw linkage quick release, you can switch bags in less than 2 minutes by one person without having to find a special wrench. This design directly reduces unproductive downtime and helps you improve overall line availability.
The main body is constructed of solid SS304/316L material and the wall thickness is fully compliant with pressure vessel safety calculations. Even if you’re handling high-temperature fluids from 120°C to 150°C, the barrels won’t deform under thermal stress and have a design life of typically 10 years or more.
Internal flow paths have been optimized by CFD simulation to reduce inlet and outlet pressure drop by 15-20% compared to conventional designs. This means that for the same pumping power consumption, you can get a larger instantaneous capacity, which directly reduces your operating costs.
The inner wall is mirror-polished, with a measured roughness of Ra <0.4 μm . When you clean, not only is there no dead angle, but also the rate of material hanging on the wall is extremely low, which is especially suitable for your hard requirement of “zero cross contamination” during the production of changing batches.
The matched high-strength perforated mesh basket has more than 60% effective open area. Even if you are faced with an instantaneous shock differential pressure of 0.3 MPa, the support basket will maintain the same geometry, preventing physical breakage of the filter bag due to support failure.
Whether your site is flanged, threaded or sanitary quick-fit, we can customize the inlet and outlet orientations to your pipe elevation. You don’t need to overhaul the piping when you get the equipment, you can just put it in place and butt-lock it, eliminating additional construction costs.
The top cover is reserved with a G1/4″ size vent and pressure gauge connection. This port must be used to manually relieve residual pressure before you can open the lid. This redundant safety design helps you to avoid liquid spills in the field due to mishandling.
Quality Control for Single Bag Filter Housing
Your single bag filter housing must go through a rigorous verification process before it leaves the factory. Not only do we hold ISO 9001, CE, and FDA certifications for pharmaceutical and food grades, but we also perform a rigorous on-the-job Hydrostatic Test – a 30-minute hold at 1.5 times the design pressure – to ensure that every unit you get has no leakage from weld depths or sealing locations. We use spectroscopy for precision work. For precision work, we verify material grades by PMI and include hydrostatic test curves and $Ra$ roughness inspection records in the factory report, so your compliance audit is flawless.
Customized Single Bag Filter Housing
Standard single bag filter housings often don’t “fit” into your existing plumbing space. From SS304/316L, carbon steel to highly corrosion-resistant PP/PVDF, the material library covers your media needs. You can customize special inlet/outlet orientations, cap opening logic (triple jaws/bolts/swivel caps), and barrel thickness and reinforcement to meet ASME VIII-1 specifications (note: U-Stamp originals are not available). Whether you require 1μm or 200μm filtration accuracy, or special ANSI/JIS flange standards, we can accurately realize your CAD drawings to ensure that you can align the equipment without having to change the tubing twice when it arrives at your site.

Applications of Single Bag Filter Housing
When paint shear clumps cause holes in the surface of a car or slow bag changes slow down the line, FiltEdge’s single bag filter housing with a three-jaw quick-open mechanism and CFD-simulated drag-reducing flow paths allows your operators to perform maintenance in less than 120 seconds, ensuring that your paint line won’t be shut down for a bag change. Runner optimization reduces paint loss and helps you keep your paint pass rate within preset targets.
FiltEdge uses a reliable single bag filter housing with a mirror-polished inner wall (Ra <0.4μm) and no dead space, reducing your rinse water consumption by more than 30% when switching between batches. With no material hanging on the walls, you don’t have to worry about the risk of recalling entire batches due to cross-contamination, which directly significantly improves the key food safety inspection rate of the entire production line.
Loss of precious metal catalysts or leakage of toxic solvents due to seal failure is one of the most costly and dangerous aspects of fine chemicals.
This design helps you seal off the path of loss for expensive materials. You no longer have to pay for catalyst loss due to side leaks, and you avoid the risk of shutdowns due to VOCs during environmental inspections.
For small dosages that leave a lot of residue, or for large equipment that doesn’t fit into a compact lab space, FiltEdge offers a single bag filter housing with customized inlets and outlets in the Size 03/04 compact design, a custom solution that allows you to put it in place without having to remove the existing plumbing and saves you thousands of dollars in construction costs. The extremely small internal dead volume helps minimize the loss of expensive liquid residue, so every drop of liquid can be converted into a productive output for you.

A: Our single bag filter housing will fit any standard size 01-04 bag. However, I have to remind you that the sealing rings of many third party bags are not as hard as they should be, and can be easily punctured under high pressure, resulting in side leakage. In order to prevent you from wasting your money on a bunch of scrap, I suggest you send me your consumable specifications when you make your first selection, so that you don’t let the poor quality filter bags ruin the filtration accuracy of the whole machine.
A: Well, to be clear, the cost of obtaining that certification is extremely high, and you pay for it in the end, so FiltEdge ‘s approach is to implement the ASME VIII-1 specification in its entirety: from wall thickness calculations, to weld inspections, to even PMI material sampling, we do it all. Our single bag filter housing gives you the same level of safety, but saves you the “brand premium” license fee.
A: Those single bag filter housings on the market that are designed to save material and have wall thicknesses that step over the qualification line will basically deform permanently when they encounter the water hammer effect (instantaneous pressure shocks). We give you a 20% safety margin for the wall thickness of the cylinder. Even if the instantaneous pressure fluctuation exceeds the rated pressure, the redundant structural strength ensures that the barrel body will not expand the bag and the flange will not warp.
A: Intergranular corrosion is the death knell of many stainless steel installations. For this single bag filter housing, we not only provide a material report (MTR), but also use argon gas shielded welding and post-weld passivation treatment to completely remove the chromium-depleted layer in the heat-affected zone in the critical weld seams. If you require, we can provide penetration testing (PT) or ultrasonic testing (UT) reports for individual units to ensure that you are not getting a “pressure vessel” with hidden defects.
FiltEdge ‘s single bag filter housings are shipped with a customized pearl cotton cover of at least 15mm in thickness and encased in a fumigation-free wooden crate. If the sealing surface is found to have non-human impact upon arrival, we will directly initiate a remote claim and send the core sealing assembly by SF, never letting transportation problems delay your on-site work schedule.
